DEFINITION

Classification: 409/85

Reproducing means:

(under subclass 79) Apparatus particularly adapted to generate substantially the form of a separate member, i.e., a pattern member, of the same or different size.

(1) Note. An image on a planar element may be considered to be the form of the separate element for this subclass.

(2) Note. Included herein is shaping in which the product corresponds to the shape of the pattern element in a relief or intaglio relationship or in which the shape of the pattern member is produced repeatedly on the same workpiece.

(3) Note. Production of a mirror image of the pattern is included in this subclass.

(4) Note. A change in part of the dimensions of the workpiece without a corresponding change in the remaining dimensions is included in this subclass, e.g., the reproduction of a peripheral surface on a flat plate without corresponding change in the thickness thereof.
